ARM 7 - your comments please!

Hi group,

I am new to ARM7 microcontrollers and would like to hear from experienced people what they recommend. I saw that the Philips ones are pretty popular but ST have a built-in 1.8V regulator. What chip would you recommend? Are there any ARM7 with more than 64KB Ram and 1MB Flash? I am not very keen in soldering - in fact I would prefer a ready made and pretty small board with a chip on it so that I only need to add power to get my first project going. Perfectly it should have a mounted graphic LCD module and if possible 128KB Ram and 4MB Flash or more. How good is the gcc compiler tool-chain for the ARM, code density etc? Does everything work as expected? How about malloc and related functions? Does the C++ frontend work for the ARM? As a fan of Modula

- I couldn't find it - any project with a Modula compiler? Anything else you may want to share?

Best thanks in advance!

There is a gnu Modula-2, but for a larger user base, you might want to look at the FreePascal ARM efforts,

That is sensible. It is not realy worth making your own board these days. Gone are the days of MCU in 40 pin DIl sockets.

Buy a kit! Why do you need so much memory? What is the project

Not that good compared to the commercial compilers. (I assume you mean C or C++) However if it is for your own use it is OK.

A lot of embedded coding standards prohibit the use of Malloc.

Whilst Modula is theoretically a good language finding a good implementation is another matter. Also I think you will find that 99% of the support for ARM will be in C or C++ Certainly all the free examples from the chip vendors.

Your ]best bet is to buy a dev kit.

None of us are with a BGA!!! :-)

For a first project that is a good idea.

Why so much for a first project?
